RETAINING VALVE BRACKET Filed Sept. 8, 1925 Patented Use. 10, 1929llhlll'Efl STATES VICTOR H. HARBERT, OF SPRINGFIELD, ILLINOISRETAINING-VALVE BRACKET Application filed September Retaining valves areapplied to cars to i make the movei'nent of a train of cars safe,

and to cons rve the supply of air, and this valve when and in goodworking order a does not allow all of the air to escape :trom

the brake cylinder, but retains a certain amount or" pressure thereinsuliicient to hold the brakes in a set position, while the air is beingreplenished in the train line. i l hen the air pressure in the line isincreased or replenished, if the retaining valve is in an inoperativecondition, the triple valve will automatically assume a releasedposition allowing the train to gain momentum and run out of control. litis, therefore, of the utmost importance that the retaining valve be ingood Working order at all times.

The practice in vogue prior to my invention was to bolt the retainingvalve through the our end wall, but this practice has been foundobjectionable in that the bolt holes in the car Wall gradually increasein diameter, d to to the service movements of the car, whereby the boltsbecome lose, thus leaving the valve and its pipe free to swing, therebyreducing the elliciency of the valve.

ll hen the retaining valve becomes detective. it is necessary to removethe bolts from the inside of the car whether it be a house 30 car oropen ear, and it the car happens to be loaded, the load must be removed.

The object of my invention is to provide an anchor -for a retainingvalve so mounted on the ear and oil such construction that the retainingvalve may be detached from and applied to the anchor Without removingthe load from the ear, thereby reducing the expense of repairs to aminimum, and eliminating the possibility of damage and loss of thecontents of the car.

In the drawings:

' l is a front elevation oi my anchor s, 1925'. Serial No. 55,198.

Figure 3 is a front elevation of my im proved anchor or bracket.

Fig. is a sectional view taken on the line l-d of Figure Fig. 5 a topplan view of Figure 3.

The reference numeral 1 pipe, tori'ning part of the air brake system ofthe car, to the upper end of which is secured the retaining valve 2,which is provided with the lugs or ears 3 having bolt or rivet openingsthereihrough.

My improved anchor or bracket comprises a base plate 4r having at itsupper edge a spacing member or shell 5 extending forwardly and at rightangles to said base. An apron 6 depends from the outer edge of the shelfand is spaced from and parallel to the base. but does not extend to thebottom edge of the base, as more clearly seen in Figures 2 and t.lhrough the base and below the lower edge of the apron are bolt or rivetholes 7' through which belts or rivets pass to secure the anchor to thecar wall.

In the shelf 5, 1. term rectangular openings 8 through which the head 9of bolts l0 ma pass, and there being a slot ll in the shelf 5communicating with these openings 8. to permit the oi? the body of thebolts into the elognated slots 12 formed in the apron 6, whereby thebolt heads 9 may pass down between the apron 6 and base as clearly shownin Fig. 2.

The anchor is secured firmly to the car Wall. In attaching the retainingvalve to the anchor the bolts may be positioned loosely in the slots 12and when the valve is in proper position, the bolts are aligned With theholes in the ears 3 and the valve then pushed onto the bolts and thenuts 13 screwed tightly on i the bolts, firmly securing the valve to theanchor. It will be noted that all operations necessary to attach orremove the valve from the car are performed outside of the car.

In the first installation, the bolts 10 are firmly secured near the topof the slots 12 so 1 L o designates the air that, in the event of anyshortening of the pipe 1, due to breakage, re-threading, etc., of thepipe, the bolts 10 may be lowered in the slots to take care of anyvariations of length in the pipe, within reasonable limits, withoutdisturbing the original position of the anchor- What I claim is 1. Aretaining valve anchor comprising a base, an apron extending downwardlyfrom the top of and spaced from and parallel with and terminating shortof said base, elongated slots in said apron opening at the top of saidbase, elongated slots in said apron, terminating in enlarged openings insaid shelf.

a 4. A retaining Valve anchor, comprlslng a base adapted to be securedto a support, a

spacing member extending forwardly from the top of said base, and aplate depending from said spacing member and spaced from the base, saidplate being adapted to support a retainingvalve.

5. A retaining valve anchor, comprising a base'adapted to be secured toa support, a

spacing member extending forwardly from the top of-the base, and aretaining valve supporting plate depending from said spacing member andspaced from the base and terminating short of'the bottom edge of saidbase.

6. A retaining valve anchor, comprising a base adapted to be secured toa support, a spacing member extending forwardly from the top of saidbase, a retaining valve supporting plate depending from said spacingmember and spaced from the base and bolt openings to receive boltswhereby the retaining valve is secured to said plate.

7 A retaining valve bracket comprising a base portion adapted to besecured to a support, a spacing portion extending forwardly in the otherside of the plate for receiving the valve anchor bolts.

9. A retaining valve bracket comprising an. inverted U-shaped member,one leg of the member being extended beyond the plane of the perimeterof the other leg and having apertures to receive bolts for securing thebracket to a car wall, while the other leg of the member is apertured toreceive valve anchor bolts.

In testimony whereof I affix my signature.
